A model of clinker capacity expansion

Article Abstract:

A model was formulated to create an optimal plan for clinker capacity expansion. The model addresses the problem by decomposing it into to two subproblems, the first deals with the optimal number, size and time scheduling of new kilns if they are to be centrally located while the second deals with the decision involving location of new kilns. In the first subproblem, an optimal solution involves maximizing cash flow's net present value (NPV) produced by the introduction and operation of new kilns subject to capacity and demand constraints.

Joint planning of combined heat and power and electric power systems: an efficient model formulation

Article Abstract:

A study presents a reformulation method of addressing joint planning problems of combined heat and power and electric power systems. Linear programming and mixed integer linear programming are used to formulate JPP problems. A particular JPP problem is formulated where a region's total cost of meeting time-varying demands of electricity and thermal energy is to be met. Results reveal a reformulation method that reduces solution time to a factor of two to five.

A location-distribution application for a beer company

Article Abstract:

A model defining problems of new brewery location and malt and beer distribution is examined. The model's variables and parameters include yearly amount of beer shipped from brewery to customer zone, yearly amount of malt shipped from malt plant to brewery, alternative brewery locations and customer zones. It is shown that the new brewery will optimize operations with a capacity level of 20% based on transportation costs.
